Question

How would I factor 2x^2+400x=0

Answer 1

So far I factored out the GCF(2)
But I have no idea what to do next...

Answer 2

@Cosmichaotic can you help me?

Answer 3

Well you have another factor you can factor out besides just the 2.

Answer 4

Oh x

Answer 5

Correct!

Answer 6

so that means the two solutions would be x=0 and x=-400?

Answer 7

-200*

Answer 8

\[2x ^{2}+400x = 0\rightarrow 2x(x+200)\]
Where if you set x = 0 you get 0 and if you set x = -200 you also get 0, so that is absolutely right.
